D11xL50.7xD14xL105 Hard alloy flat bottom drill bit is tool designed specifically for high-precision and high-efficiency deep hole drilling, especially suitable for machining applications that require flat bottom .

1. Main features:

Hard alloy material: Hard alloy (HM) material has extremely high wear resistance, thermal stability, and fracture resistance, allowing flat bottomed drill bits to maintain high performance and long life under harsh processing conditions.

Flat bottom design: The cutting end of the drill bit is designed as flat bottom, which can ensure that the bottom of the hole is flat during the machining process

Internal cooling design: The internal cooling channel can directly deliver the coolant to the cutting area

Accurate temperature control and chip removal: Its internal cooling system can effectively reduce cutting temperature, maintain stable machining environment, and ensure smooth chip removal, reducing troubles during the cutting process.

Applications

The solid HM flat bottom drill is widely used in aerospace, medical devices, mold manufacturing, automotive parts, and general machinery. It is particularly suitable for deep-hole drilling tasks with strict requirements on hole flatness, diameter precision, and depth control. Applicable to stainless steel, carbon steel, aluminum alloys, titanium alloys, and other metal materials.
